I made a little test case. To isolate things to just how array-valued
parameters are programmatically set and accessed, I used a dummy annotator from
the uimaj-examples project called the "RoomNumberAnnotator" - the version I used
has no "initialize" of its own (so it didn't do anything in its initialize
method).
Then I did the following "driver" code, modelled after your code, except I only
did one parameter - the string array valued p1:
public static void main(String[] args) throws
ResourceInitializationException {
AnalysisEngineDescription_impl primitiveDesc = new
AnalysisEngineDescription_impl();
primitiveDesc.setPrimitive(true);
primitiveDesc.getMetaData().setName("test of setting string array
parameters");
primitiveDesc.setAnnotatorImplementationName("org.apache.uima.tutorial.ex1.RoomNumberAnnotator");
ConfigurationParameter p1 = new ConfigurationParameter_impl();
p1.setMultiValued(true); // needed to have this parameter take an array of
values
p1.setName("AttributeList");
p1.setDescription("Attribute List");
p1.setType(ConfigurationParameter.TYPE_STRING); // This specifies the type
of each element of the array
primitiveDesc.getMetaData().getConfigurationParameterDeclarations().setConfigurationParameters(
new ConfigurationParameter[] { p1 });
// This sets the configuration parameter to a value which is an array of
Strings, "v1" and "v2"
primitiveDesc.getMetaData().getConfigurationParameterSettings().setParameterSettings(
new NameValuePair[] {
new NameValuePair_impl("AttributeList", new String[] {"v1", "v2"})}
);
TypeSystemDescription typeSystem = new TypeSystemDescription_impl();
primitiveDesc.getAnalysisEngineMetaData().setTypeSystem(typeSystem);
// For testing - make an UIMA Analysis Engine from this specification
AnalysisEngine ae = UIMAFramework.produceAnalysisEngine(primitiveDesc);
// Get the UIMA Context from where we can try getting the configuration
parameter settings
UimaContext context = ae.getUimaContext();
// Get the configured value
Object v = context.getConfigParameterValue("AttributeList");
System.out.format("Type of object returned is %s, object is %s%n",
v.getClass(), v) ;
// print out the individual strings in the array
String[] av = (String[]) v;
System.out.format("The two values are %s and %s%n", av[0], av[1]);
}
I ran this and it printed out:
Type of object returned is class [Ljava.lang.String;, object is
[Ljava.lang.String;@45a36ab6
The two values are v1 and v2.
No errors were thrown.
Hope that example helps.
